摘    要:由于道路建设,原有土壤被扰动,形成了一种新的人为土-路域土壤。文章对路域土壤的成因和特点进行了阐述,并以呼集高速公路卓资段的实例来说明路域土壤的特点。研究分析了路域土壤的理化特性,土壤污染特征。结果表明:路域土壤形成过程中,土壤的粉沙粘粒含量、有机质和养分含量趋于下降、pH值趋于升高;土壤理化性质的恶化是土壤粉沙粘粒和有机质被道路建设所影响的结果,进而造成土壤粗粒化,并且路域内部有潜在土壤污染的可能.

关 键 词:路域  土壤理化性质  重金属

Abstract:During the construction of expressway, the natural vegetation and soil had been destroyed, soil quality has degraded. This paper takes an existing expressway road area soils as a case study, and give a summarization on the formation and characteristics of road area soils. This research results showed that in the degradation process of the soils, silt content, organic matter, available nutrient were gradually reduced but soil rigidity and pH rose. Worsening of the soil properties resulted from decreasing of silt and clay particles and organic matter caused the coarsing of soil particles. The pollution characteristics of heavy metals in soils of different function positions of road area were studied, and made an objective assessment of the pollution of heavy metals, which can offer an useful background material for subsequent research.
Keywords:road area  soil physical and chemical properties  heavy metal
